[RESEND][PATCH 6/7] xfs: Remove code handling bio_alloc failure with __GFP_WAIT

[Nikanth Karthikesan <knikanth@xxxxxxx>]

Resending as I accidentally missed Jens earlier.

Jens, can you merge this as well.

Thanks
Nikanth

Remove code handling bio_alloc failure with __GFP_WAIT.
GFP_NOIO implies __GFP_WAIT.
